TRIGGER MECHANISM.

Specification of Letters Patent.

Patented Oct. 26, 1909.

Application filed May 4, 1907. Serial No. 371,76 6.

To all whom it may conccm: I

Be it known that I, ELZY B. WILLIAMS, a citizenof the United States, anda resident of St. Joseph, in the county of Buchanan and State ofMissouri, have invented a new and Improved Trigger Mechanism, of whichthe following is a full, clear, and exact description. V

. The invention relates to fire arms and its object is to provide a newand improved trigger mechanism provided with a very sensitive auxiliarytrigger on the usual or main trigger, to securely lock the main triggerand hammer in firing position, and to permit an easy and quick releaseof the hammer for firing purposes.

The invention consists of novel features and parts and combinations ofthe same, which will be more fully described hereinafter and thenpointed out in the claims.

A practical embodiment of the-invention is represented in theaccompanying drawings forming a part of this specification, in whichsimilar characters of reference indicate corresponding parts in all theviews.

Figure 1 is a side elevation of the improvement as applied to a breechloading fire arm, the stock of which is shown in section; Fig. 2 is alike view of the same showing the hammer in a cooked position; Fig.

. 3 is an enlarged edge view of the improvement; Fig. 4 is a' si eelevation of'the same, a part of the cover plate being removed,

7 and Fig. is a side elevation of the improve- I ment showing the partsin another position.

The fire arm on which the improvement is applied consists of the usualstock A, the barrel B, the hammer C, hammer spring C, trigger D, triggerspring D, breech block E and the lever F for operating the breech blockE and for forming a trigger guard.

On the finger piece of the main trigger D is rigidly secured a plate orbracket G on which is fulcrumed at H an auxiliary trigger H pressed onby a spring H and limited in its rearward movement by a stop pin Hsecured on the plate G. The rear end of the auxiliary trigger H isprovided with a catch H adapted to engage a shoulder I formed on theupper and free end of a lever I fulcrumed at I on the plate G, the saidlever I being provided with a suitable knob or handle I under thecontrol of the operator, for imparting a swinging motion to'the lever I,to engage the shoulder I thereof with the catch H*, as hereinafter morefully explained- The lower end of the le er I is swinging movement atthe time the hammer C is in a cooked position, and the auxiliary triggerH is pressed by the operator for firing the fire arm.

The operation is as follows: When the fire arm is loaded and the severalparts are in the normal position illustrated in Fig. 5, and it isdesired to cock the hammer C, and to operate,

it with the auxiliary trigger, the operator takes hold of the knob 1 andpresses the same forward to impart a forward swinging motion to theupper part of the lever 1, whereby the lower part thereof swingsrearwardly and'brings the hook K into position for engaging the pin N.The hammer is now drawn rearwardly which cocks the same and at the sametime engages the hook K with the pin N. When now pressure is made on theauxiliary trigger H, the catch H is released from the shoulder I, andthe spring J swings the lower part of the plate I forwardly. The hook Kis however in engagement with the pin N, which makes a backward pull onthe trigger and releases the hammer and discharges the fire arm.

When it is not desired to use the auxiliary trigger, the hammer ismerely cooked without moving the knob I and when so cocked a rearwardpressure on the trigger will release the hammer.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:

. 1. A trigger mechanism for fire arms comprising a main trigger, aplate pivoted thereon and provided with a shoulder, an auxiliary triggerhaving a catch for engaging the shoulder, a spring pressing the lowerpart of the plateand normally acting to swing said lower part forwardly,a hook pivoted to said lower part, a fixed pin for engagement by thehook, and a spring nor- I mally acting to press the hook into engagementwith the pin.

2. A trigger mechanism for fire arms comprising a main trigger, a pin onthe breech block lever, a plate pivoted to the main trigger, anauxiliary trigger for engaging the plate to retain it in forwardposition, a hook pivoted to the lower end of the plate for engaging thepin, a spring normally acting to move the lower end of said platet'orwardly,and a handle on the plate for the purpose set forth.

3. A trigger mechanism for fire arms comprising a main trigger, a springpressed lever pivoted to the main trigger, an auxiliary trigger forengaging and locking the said lever, a catch on the lever, and a fixedpin for engagement by the catch.

In testimony whereof I have signed my 15 name to this specification inthe presence of two subscribing Witnesses.

ELZY R. WILLIAMS.
